What makes it interesting?
This bridge will consist of two concrete corkscrew ramps approaches that use multiple multi-level, intermediate piers to stack the deck into the small right-of-way. The ramps were cast-in-place using falsework and shoring that could be flexible enough to meet various layouts for different pour sections. Each pier and slab pour made continually-shifting radius grades to match the main-span connection and meet ADA standards.
How HCSS Software assisted with this project
By utilizing HeavyBid software, Gibbs & Register, Inc. was able to actively manage all of the various vendor and specialty subcontract scopes and prices in the quotes system. They then compared those items to Gibbs & Register, Inc.’s self-perform pricing to ensure the best coverage and price for a low-bid estimate that left only $35,000 on the table for a $7.425 million project!
The Kissimmee Trail Bridge over John Young Parkway is a “Most Interesting” project for a plethora of reasons.
Some of the unique features of this project include: the 220-foot main span that, when finished, will have solar-powered, lighted signage welcoming visitors to the City of Kissimmee, and beautifully decorated architectural columns that are steel framed and clad with Densglass and stucco at the base and precast, faux-brick panels to their peaks which sit 60 feet above the ground. There is a 180-foot extension of the 12-foot by 8-foot, triple-box culvert that will allow the quarter-mile extension of the bicycle trail.
The main-span will be enclosed with stainless steel mesh that serves to protect the traveling public below, there are tubular steel arches for the mounting of the lighted signs, seamless metal roofing of the tower caps, and the decorative, lighted bollards that will grace the approaches to this signature span.
These are all items that make this pedestrian crossing interesting, but what makes it a one-of-a kind project that says this is a “Most Interesting” project are the approaches to the main span themselves. The approaches for the Kissimmee Trail Bridge consist of two separate, cast-in-place concrete corkscrew ramps that utilize multiple multi-level, intermediate piers to stack the 15-inch-thick deck into the small right-of-way while spanning an existing drainage canal.
Due to the tight radius of the corkscrew and the need to maintain an ADA-compliant transition from the existing grade to the main span, these approaches had to be cast in place utilizing falsework and shoring that could span the existing canal at certain pours, and be flexible enough in configuration to meet the various layouts for the differing pour sections. The effort utilized to ensure the accuracy of each pier and slab pour to make the continually-shifting radius grades match the main-span connection while maintaining ADA compliance was phenomenal. These approaches with their multi-level piers, along with the varying array of finishes and technologies, make the Kissimmee Trail Bridge a Most Interesting project.
